During the upgrade/downgrade some minor alarms and conditions display and then clear
automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than
BLSROSYNC, which will clear when the upgrade/downgrade of all nodes is complete. If any
other service-affecting alarms occur, Cisco recommends backing out of the procedure.
A four-node BLSR can take up to five minutes to clear all of the BLSROSYNC alarms. Allow
extra time for a large BLSR to clear all of the BLSROSYNC alarms. Refer to the Cisco ONS
15454 Troubleshooting Guide for information about alarms.
The span upgrade process resets the line's CV-L threshold to factory default. The CV-L threshold
is reset because the threshold is dependent on line rate.
The Span Upgrade option will only be visible and available if the hardware necessary for the
upgrade is present; for example, no upgrade is possible from an OC48 span unless XC10G cards
are installed in the nodes at both ends of the span.
